Red Hat Bugzilla – Bug 1569515
All network bridges switch to br-ex by default
Last modified: 2018-08-29 12:36:17 EDT
Description of problem: I'm loosing connectivity to ObjectStorage and Ceph nodes because of: https://github.com/openstack/tripleo-heat-templates/commit/1dec175241c7e5f3c85dbe0cb1d38909e1d52308 br-storage gets renamed to br-ex This change will break all deployments that used default templates.
Lukas - just trying to understand the issue. Can you indicate which default templates are being used? Also which version are you upgrading from? None of the templates define br_storage AFAIK. In fact we had a recent bug in OSP-10 in which the bridge_name in ceph_storage.yaml was not defined and it defaulted to null - https://bugzilla.redhat.com/show_bug.cgi?id=1562810 Also its not necessary to define a bridge on ceph nodes. We have a BZ to change the default storage templates to remove the bridge. https://bugzilla.redhat.com/show_bug.cgi?id=1569263 It is true that in OSP-12+ "bridge_name" now defaults to br_ex in all cases (not just for controller and compute). The ceph nic_config files would have to explicitly define the name of the bridge and not use "bridge_name" (if a bridge was used although its not necessary).

None > of the templates define br_storage AFAIK. The single-nic-vlans templates had "br-storage" for the Ceph nodes. Now that the roles have been unified in one role.role.j2.yaml file, the Ceph nodes have the same bridge_name token for the name of the bridge, which is replaced with "br-ex" by default. The single-nic-vlans templates aren't considered a production template (really it's intended for VM deployments or POC that we don't really expect to be upraded). I can submit a fix that checks for the Ceph role, but a workaround is to use a copy of the original NIC configs instead of using the new NIC configs rendered by Jinja when upgrading.
Fix in progress. Reducing severity as there is a workaround.
